Then we formulate scalar and gauge sector, neutrino mass matrix and lepton flavor violations. In our gauge sector, $Z$-$Z'$ mixing appears after spontaneous symmetry breaking and we investigate constraint from $\\rho$-parameter. In addition we discuss $Z'$ production at the large hadron collider via $Z$-$Z'$ mixing, where $Z'$ tends to dominantly decay into heavy neutrinos.","authors_text":"Hiroshi Okada, Takaaki Nomura","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-12-20T10:35:49Z","title":"Seesaw model with hidden $SU(2)_H \\times U(1)_X$ gauge symmetry"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.08473","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:c887398399a932d73fdd0017faae5ebba2f7f74f0e851591589206b14b6f381f","target":"record","created_at":"2026-07-05T00:25:08Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"e2b7eabd45c90ebf700787b02ca8f4c7c7149dc6d2ed3c0ef04a1b66cba1ebd3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-12-20T10:35:49Z","title_canon_sha256":"54ba4a3769b852bfabcceb9a6c4f2aeb5673e0fcb5d9aa985b8d5aa2ba8e6302"},"schema_version":"1.0","source":{"id":"1812.08473","kind":"arxiv","version":2}},"canonical_sha256":"9e98e86b3e6a4496f7e230b12addde35dc4efad7600f8654ed76f8edd636a19e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9e98e86b3e6a4496f7e230b12addde35dc4efad7600f8654ed76f8edd636a19e","first_computed_at":"2026-07-05T00:25:08.216269Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:25:08.216269Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zEVW04rlDbF8imFPWWu0DaEWedEUEQDBuCOF4PebeNS+DkVzs9azXaPU/VLvGgmSh4gA55AEdXJTh1lLshl1CQ==","signature_status":"signed_v1","signed_at":"2026-07-05T00:25:08.216698Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.08473","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c887398399a932d73fdd0017faae5ebba2f7f74f0e851591589206b14b6f381f","sha256:81d7122c564860285e7236af6f08821007f391e1cb462dadd0292b13c5726c40"],"state_sha256":"5566a964da73ec43a1b4f558d35d31e3841cb84e26b8020327e8cb507d1f1857"}
